Belonging to the material processing field, the invention discloses an extrusion molding horizontal transfer correction device and a material production device. The correction device includes a firstconveyor belt and a second conveyor belt arranged collinearly, the second conveyor belt is disposed at the output end of the first conveyor belt, and the first conveyor belt is higher than the secondconveyor belt. A plurality of horizontally arranged parallel grooves are disposed at interval on the second conveyor belt, a first baffle plate is disposed between the first conveyor belt and the second conveyor belt to interfere materials, at least parts of the randomly arranged materials are corrected to arrangement along a horizontal direction or a direction close to horizontal, so that most materials can fall into the grooves. A third baffle plate is mounted above the second conveyor belt to interfere materials not falling into the grooves, so that the materials not falling into the grooves can fall into the grooves. The device can enables overall materials to fall into a hob cutter horizontally and synchronously for grain cutting, thus greatly improving the uniformity and regularity of the grain cutting.
